Abstract: A double-anchor strapless dildo has an insertion shaft (1) formed for insertion in a vagina of a first female by a second female to whom the insertion shaft is double-anchored with an anal anchor (4) and a vaginal anchor (5) on an attachment base (2). The insertion shaft is formed and optionally surfaced for desired contact with erogenous areas of the vagina of the first female. The vaginal anchor is formed and optionally surfaced for desired contact with erogenous areas of the vagina of the second female. For combining attachment rigidity and contact with erogenous areas of the second female, the attachment base has a vaginal-anchor hook (11) formed for engaging bony structure of the symphysis pubis and for engaging erogenous entry walls of the vagina of the second female while being double-anchored to the second female with the anal anchor and the vaginal anchor.
